I know this is a really old post but I couldn't help but answering it because it seemed it didn't get the full answer. The task is pretty simple you want to resize the text of the Tab Control's pages but if you select the Tab Control you are selected the Tab Control AND all the controls on the tab (which is really annoying, copying and pasting just a tab copy and pastes all the controls for example). So here is how you deal with Tab Controls.... Make them a Typedef.
Then when you want to modify or just copy the Tab Control you go to the Typedef. For working with characteristics of the Tab Control like Color/Font Size etc, you simply change it on the typedef. Now it has to be a Strict Type for those changes to take effect. One annoyance of doing this is that your size of the Tab Control and ALL the attributes will revert to what's in the Strict Type Def. But I usually change it BACK to a regular Type Def for another annoyance: Adding Pages to a strict Type Def Tab Control. When you do this, sometimes it does weird things with an already existing Tab Control like moving controls off or onto other pages. But if you do this when it is a Typedef, it doesn't do that. But for the question at hand, it is simple. Go to the typedef, make the changes, and save (as a Strict Typedef) and go back and then go back if you want to to turn it back to a regular Type Def, if you want
